Official Title: A Randomized Controlled Trial of Rigid Versus Semirigid Thoracoscopy in the Evaluation of Exudative Pleural Effusions
Brief Summary: Rigid thoracoscopy is an established procedure for the performance of pleural biopsies for undiagnosed pleural effusions. The semirigid thoracoscope is a relatively new instrument designed for the same purpose which is claimed to be more user-friendly. The two devices have not been compared in a head-to-head trial in published literature. The investigators attempt to conduct a randomised comparative trial between the two devices.
